Hacks! An investigation into aimbot dealers, wallhack users, and the million-dollar business of video game cheating

Zero is a customer service representative for one of the biggest video game cheat providers in the world. To him, at first, I was just another customer. He told me that the site earns approximately $1.25 million a year, which is how it can afford customer service representatives like him to answer questions over TeamSpeak. His estimate is based on the number of paying users online at any given time, the majority of whom, like me, paid for cheats for one game at $10.95 a month. Some pay more for a premium package with cheats for multiple games.

As long as there have been video games, there have been cheaters. For competitive games like Counter-Strike, battling cheaters is an eternal, Sisyphean task. In February, Reddit raised concerns about lines of code in Valve-Anti Cheat (VAC), used for Counter-Strike and dozens of other games on Steam, that looked into users’ DNS cache. In a statement, Gabe Newell admitted that Valve doesn't like talking about VAC because “it creates more opportunities for cheaters to attack the system." But since online surveillance has been a damning issue lately, he made an exception.

Newell explained that there are paid cheat providers that confirm players paid for their product by requiring them to check in with a digital rights management (DRM) server, similar to the way Steam itself has to check in with a server at least once every two weeks. For a limited time, VAC was looking for a partial match to those (non-web) cheat DRM servers in users’ DNS cache.

I knew that cheats existed, but I was shocked that enough people paid for them to warrant DRM. I wanted to find out how the cheating business worked, so I became a cheater myself.


Gabe Newell: Valve Anti-Cheat does not look at your browsing history

Two days ago, Reddit user theonlybond posted lines of code from Valve Anti-Cheat (VAC), the software Steam uses to curb online cheating, accusing it of scanning users' internet browsing history and sending it back to Valve. Other users were quick to point out that the accusations were unfounded, but the discussion got serious enough for Gabe Newell to make an official statement.
